Bump Stop - Black - for RB13 series Rebreather Valves

RB13/01/BLK - Black Bump Stop for RB13 series AP Rebreather Cylinder Valves

Replacement part for: 

 • RB13, RB13A/G & RB13A Rebreather Cylinder Pillar Valves

Different colour bump stops (and handwheels) are available for AP pillar valves on this site.

These include Red, Blue, Green and Black - which are useful to indicate different gas mixes:

eg. Red (for toxic/hypoxic-at-the-surface mixes), Blue or Black (nitrox/trimix diluents), Green (100% O2), Black (Air or other diluent mixes).

Oxygen Clean Note: Although it is less critical than for internal valve parts, it is good practice to clean replacement bump caps (and handwheels) before fitting to oxygen clean valves intended for use with gas mixes of 23.5%+ oxygen content.

It is essential that you correctly label your cylinders with the gas mix content.
